LIQUID DISCHARGE APPARATUS AND LIQUID DISCHARGE METHOD

摘要

PROBLEM TO BE SOLVED: To provide a liquid discharge apparatus for extracting a suspension having stable concentration with a simple structure at a low cost and a liquid discharge method. SOLUTION: The liquid discharge apparatus for extracting a suspension containing particle components each having different specific gravity using a syringe and a plunger has a recessed part formed in a nearly center part of a first surface facing the plunger direction of the syringe and a pipe mounted toward the outside of the syringe in the first surface from the recessed part and for extracting the suspension in a part away from the first surface. The liquid discharge method for extracting the suspension containing the particle components each having the different specific gravity has a step for giving pressure to the suspension and a step for extracting the suspension in the syringe from a part away from the first surface.
